Hopefully they find a way to include luna that is not just a redoing of existing episodes. I would not want her to be a one trick pony The obvious option, that kinda is redoing things, is to make "The Great and Powerful Trixie" a recurring character as luna's student, just as twilight is Princess Celestia's. Though were would she be based out of? Canterlot or maybe renovate the ruins seen in season one in the forest
